Answer:
y = 2
Step-by-step explanation:
Using the sine ratio and the exact value
sin45° = , then
sin45° = = = ( cross- multiply )
y = ( )² = 2
Answer:
x = 30° ; y = 45°
Step-by-step explanation:
Angle subtended by the diameter on any point of the circle is 90°. So,angleRSP = 90°
angleRST = 120° (given)
But,
angleRST = angleRSP + anglePST
In triangle PQR , PQ = RQ (given)
Hence , it is an isosceles triangle. As it is an isosceles triangle , the base angles are equal.
=> anglePRQ = angleRPQ = y°
anglePQR = 90° (Angle subtended by diameter on any point of circle is 90°)
According to Angle Sum Property of Triangle,
anglePRQ + angleRPQ = anglePQR
Compound interest sequence
I think the answer should be 25 because if you multiply 2.5 by 10. Technically it means moves 10 to the right.
Answer:
A 29 is the answer to the problem
